The Philco model 57, was my mother's first radio. It used an autodyne converter and regenerative IF setup. There was a knob on the back, but it was a band selector. The regeneration setting was a trimmer on the back of the chassis. The Philco model 80, 84 and 37-84 was similar. They were referred to as Philco Jr's.
